“…It has been reported that oleuropein reduces anxiety responses in rats suffering from post-traumatic stress disorder [47]. Additionally, vitamin E (50 mg/kg) and Se (0.3 mg/kg) reduced cortisol in sheep under heat stress [48]. However, in pigs, following transport stress, the supplementation of 200 mg/kg of vitamin E was not enough to reduce cortisol, with supplementation with oregano essential oil having a greater effect.…”

Olive tree leaves are characterized for having not only a potent antioxidant power but also effects on glucose and lipid metabolism. The impact of the individual oleuropein (OLE), vitamin E + Se (VE), or a combined supplementation of oleuropein, vitamin E, and selenium (VEOLE) was evaluated on pig plasma metabolites under fasting prior to slaughter. VEOLE and OLE had lesser n-3 plasma polyunsaturated fatty acids and greater monounsaturated free fatty acids compared to control. The n-3-fatty acid mobilization was directly correlated with greater cystine and inversely with oxidized glutathione/reduced glutathione (GSSH/GSH) levels. This faster use of n-3 fatty acids might act as an indicator of glutathione synthesis mediated by an increase of cystine in plasma. Different correlations and linear adjustments were observed between plasma antioxidant power and free cystine, free glycine, free glutamine, monounsaturated free fatty acids, and total n-3. The best response to stress was found in VEOLE. Cortisol reached the greatest positive correlation with plasma total n-3 fatty acids, which suggests a faster uptake of n-3 for biological functions such as stress control or energy supply in the brain. From a practical point of view, an enhanced oxidative status as well as control of physiological stress prior to slaughter by the combined antioxidants supplementation might have positive effects on pork quality.

“…Many solid, liquid and gas oxidizers have been evaluated. Inorganic chemicals such as oxone [32] , sodium persulfate [33] , potassium superoxide [34] , potassium dichromate [35] , sodium percarbonate [36] , sodium perchlorate [37] , hydrogen peroxide [38] , sodium hypochlorite [39] , solid oxidizers such as cyclohexanone peroxide [40] and organic chemicals such as t-butylhydroperoxide [41] and cumene hydroperoxide [42] as liquid oxidizers are used. The most distinctive feature of cyclohexanone peroxide as solid organic oxidizers and cumene hydroperoxide and t-butylhydroperoxide as liquid organic oxidizers is that they can all dissolve in the organic phase or fuel, thereby directly oxidizing sulfur compounds [43] , [44] .…”

“…The FTIR spectra of WTPO before and after the desulfurization process are presented in Figure 11. The peaks observed in the region between 1035 to 1328 cm −1 correspond to the sulfoxide and sulfone derivatives, respectively [39,43,44]. Figure 11 shows that after the desulfurization process the peaks corresponding to the sulfur compounds were decreased, which confirms that they were partially removed after oxidation followed by extraction with acetonitrile.…”

Heavy fuel oils contain a high amount of sulfur. In this work, an extent amount of sulfur content waste tire pyrolysis oil (WTPO) was used as a fuel feedstock. A promising alternative oxidative desulfurization (ODS) method was applied in sulfur removal from WTPO using a S-ZrO2/SBA-15 solid acid catalyst, hydrogen peroxide (H2O2) as an oxidant and acetonitrile as an extracting solvent at varied conditions. The prepared catalyst was characterized by X-ray diffraction (XRD), Bruanuer-Emmet-Teller (BET) method and Fourier transform infrared spectroscopy (FTIR) analysis. The influence of reaction parameters such as reaction time (30-60 min), catalyst loading (0.5–1.5 wt.%), oxidant to oil mole ratio (5–15) at fixed reaction temperature 70 °C on desulfurization of WTPO were investigated. Taguchi method was selected to design the experiment for optimizing the reaction parameters by maximizing the sulfur removal efficiency. The maximum desulfurization efficiency 59.49% was obtained under optimum conditions reaction time (60 min), catalyst loading (1.0 wt.%) and oxidant to sulfur mole ratio (10:1). A catalytic S-ZrO2/SBA-15 -H2O2 oxidation system for oxidative desulfurization of waste tire pyrolysis oil using at mild reaction conditions was developed.
